sd_bus_message_skip - Skip elements in a bus message

sd_bus_message_skip() is somewhat similar to sd_bus_message_read(3), but instead of reading the contents of the message, it only moves the "read pointer". Subsequent read operations will read the elements that are after the elements that were skipped. The types argument has the same meaning as in sd_bus_message_read(). It may also be NULL, to skip a single element of any type.

sd_bus_message_skip() was added in version 240.

Functions described here are available as a shared library, which can be compiled against and linked to with the libsystemdpkg-config(1) file. The code described here uses getenv(3), which is declared to be not multi-thread-safe. This means that the code calling the functions described here must not call setenv(3) from a parallel thread. It is recommended to only do calls to setenv() from an early phase of the program when no other threads have been started.

On success, sd_bus_message_skip() returns 0 or a positive integer. On failure, it returns a negative errno-style error code. Errors Returned errors may indicate the following problems: -EINVAL The m parameter is NULL. -EBADMSG The message cannot be parsed. -EPERM The message is not sealed. -ENXIO The message end has been reached and the requested elements cannot be read. -ENOMEM Memory allocation failed.
